2-Aryl-2-fluoropropionic acids were prepd. by treatment of either Et a-hydroxycarboxylates or cyanohydrin O-silyl ethers with diethylaminosulfur trifluoride and subsequent hydrolysis. The Me ester of 2-fluoro-2-(4-isobutylphenyl)propionic acid (\"a-fluoroibuprofen\") was submitted to an enzymic racemate resoln. [on SciFinder (R)]
